ANDREW A. UNDERWOOD, ATTLEBORO, MASSACHUSETTS, ASSIGNOR T MOSSIBERGCORPORATIOIY, A CORPORATION CONSTRUCTION FOR SPOOLS OR REE'LS.

Application filed February 17, 19%. Serial No. 88,725.

This invention relates to construction for,

spools or reels and more particularly to such devices adapted to carry awinding of metal wire in the process of annealingthe wire.

One of the objects of the invention is to provide a construction of theabove nature which is practical and eflicient and capable 7 of meetingthe requirements of use in a a construction of the above nature whichiscapable of withstanding the annealing heat a without having itsefliciency, impaired.

barrel member 10 which may be formed in Other objects will be in partobvious or in part pointed out hereinafter.

The invention accordingly consists in the features of construction,combinations of elements, and arrangements of parts as will beexemplified in the structureto'he hereinafter described and the scopeof. the application of which will be indicated in the following claims.

- In the accompanying drawing in which is shown. one of the variouspossible embodiments of this invention;

Figure 1 is a side view showing the spool or reel partly in section;

Figure 2 is an end view; 1

Figure 3 is a section taken substantially along the line 33 of Fig. 1,and

Figure 4 is a sectional view of an end portion of a spool showing amodification.

Similar reference characters refer'to similar parts throughout theseveral views of the drawing.

Referring now to the drawing-in detail, there is shown in Figure 1 ahollow metal anydesired manner; for example, by rolling a sheet of metalinto the desired hollow circular form and welding the longitudinal seam.Against the two ends of this barrel 10 are mounted and secured a pair ofmetal heads 11 and 12. These heads are substantially circular in shape,as shown in Figure 2, and are preferably provided with perfehighlysatisfactory manner. Another 0brations 12 adapted to lessen their weightwithout materially aftectin their strength. At their peripheries the heas are preferably bent outwardly slightly so as to facilitate the windingof the wire upon the reel and also for the urpose of lending rigidity tothe heads. he two heads-'11 and 12 are substantially identical inconstruction andv are similarly secured to the ends of the barrel 10.

Passing axially through the center of the barrel. 10 is a tubularbearing member 13 which projects at either end thereof through therespective heads 11 and12. This tubular member 13 provides-a suitablebearing through whicha shaft or rod ma be passed to rotatablysupport'the reel. onsidering the manner in which the ends of thistubular member 13 are secured to the heads 11 and 12, it will beseenfrom-Fi re 1 thatthe member 13 is provided wit a slightly reducedend 13? which fits snugly 1nto and passes-through a central opening inthe head 12, the outer end 13 of the member 13 projeetingoutwardly fromthe outer face of the ,head.- Resting against the outer face of the headabout this projecting end 13 of the member 13 is a flat metal ring 14whose inner diameter is a little greater than the outside diameter ofthe part 13". The annular space between the part 13 and the ring 14 1sfilled by welding 15. In this manner the welding 15 welds together thehead 12, the end of the member 13 and the ring dependable connectionbetween; the tubular member 13 and the head 12 is'thus obtained. Thering 14, securely welded both to the 14. A strong rugged andthoroughlyhead and to the member 13 provides a strong reenforcement -forthe center of the head and, moreover, the resulting outer surface of thehead at its central portion is smoothly formed Without projecting partsto interfere with the convenient handling'of the spool. 5

. Passing through the barrel 10 close up against the inner surfacethereof are a plurality of steel rods 16 shown in this instance as sixin number. These steel rods project at their endsthrough openings in theheads 11 and 12 and are rigidly secured to the heads by welding 17 atthe outer surfaces of the heads. These rods 16 thus support and centerthe barrel 10 between the two the two heads together.

These steel rods 16 are welded to the.

inner. surface of the barrel 10. Preferably each rod is welded to thebarrel at least at two points, one adjacent each end of the barrel. Thiswelding adjacent the left-hand end of the barrel, as viewed in Figure 1,'is clearly shown at 17 in Figures 1 and 3. The rods 16 are thus rigidlyjoined to the barrel, 10 as well as to each of the heads 11 and 12. Thewelding 17 is important since it prevents the rods 16 from expanding andlengthening relative to the barrel 10 and thus pushing the heads awayfrom the ends of the barrel.

The rods 16 thus dependably clamp the heads 11 and 12 against the endsof the barrel and at the same time rigidly support and center the barrelso that it is capable of dependably supporting a heavy load of wire.anger of the construction opening up between the ends of the barrel andthe inner surfaces of the heads is avoided and the consequent danger ofthe coiled wire catching in such an opening is eliminated. The heads aredependably clamped together and reenforced at their central portions bythe bearing member 13'and the weld 15, and a reel is provided which isstrong and rugged throughout and thoroughly dependable.

' In addition to the features above described, the heads 11 and 12 arepreferably welded directly to the respective ends of the barrel 10, eachat a plurality of points. This is preferably done as is best shown inFigures 1 and 3. A plurality of lugs 18 are pressed inwardly from thebarrel surface at the ends thereof. The recesses thus formed at theangle between the barrel surface and the inner surface of the head arefilled with welding 19. In this manner the barrel is securely welded tothe head at a plurality of spaced points and there is no possibility ofthese two parts separating. After the welding has been done, the weld isground off smoothly flush with the surfaces of the head and of thebarrel so as to leave a sharp clean angle as shown in Figure 1.

Referring now to Figure 4, thereis shown a modified manner of securingtogether the barrel member and the head memberf In this instance the endportion of the barrel 10 is pressed inwardly throughoutitsicireum-ference as shown at 20. The an'nular recess thus formed isfilled by welding 21. After welding the parts are ground off to leave -asharp angle between the surface of the barrel and the inner surface ofthe head so that the wire can be evenly wound. It will be seen that thebarrel is dependably joined to the head against any possibility ofseparation anel moreover, that the thickness of welding material 21provides a substantial reenforcement. In this instance the rod 16 may ormay not be employed as found desirable.

As man possible embodiments may be made'of t e above invention, and asmany changes might be made in the embodiment above set forth, it is tobe understood that all matter hereinbefore set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not i'nalimiting sense.- i
